Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically a steel gate for water conservancy projects. Background Technology

[0002] In water conservancy engineering systems, steel gates, as key water control facilities, are widely used in various hydraulic structures such as reservoirs, sluices, and hydropower stations. Their core function is to precisely regulate water flow and water level according to the operational needs of the project. At the same time, they undertake multiple important tasks such as flood control, irrigation, water supply, and navigation, and are the cornerstone for ensuring the safe and stable operation of water conservancy projects and maximizing their comprehensive benefits.

[0003] However, most existing steel gates are straight-plate structures, which makes the middle of the gate easily deformed by water impact, resulting in a shorter service life. At the same time, existing gates lack sealing mechanisms, which leads to water leakage during use and poor water-stopping effect. In order to solve the above problems, this utility model designs a steel gate for water conservancy projects. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a steel gate for water conservancy projects, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel gate for water conservancy projects, comprising a water channel, a support tightly fitted inside the water channel, a gate slidably connected inside the support, a middle plate tightly fitted to the rear end of the gate, an inner plate tightly fitted to the rear end of the middle plate, a truss tightly fitted to the rear end of the inner plate, a screw hinged to the top of the gate via a hinge block, a nut meshing with the outside of the screw, a secondary gear fixed to the top of the nut, a turntable fixed to the top of the secondary gear via a support ring, a sealing groove fixed to the outside of the gate, a sealing strip slidably connected inside the sealing groove, a guide rail provided inside the support, and an anti-blocking protrusion fixed inside the lower end of the guide rail.

[0006] Preferably, the water channel is provided with a pouring trough, which is closely fitted to the bottom of the support. The left and right ends of the support are fixed with connecting plates, each connecting plate is fastened to the water channel by bolts, and each support is fixed with a support plate at the top.

[0007] Preferably, a support frame is fastened to the top of the support plate by bolts, a solar panel is fixed to the top of the support frame, a protective box is fastened to the top of the support frame by bolts, a controller is fixed inside the protective box, a battery is fixed to the rear end of the controller, and a sealing ring is fixed to the top of the protective box, the sealing ring being tightly fitted with the support ring inside it.

[0008] Preferably, a motor is fixed to the top of the support frame, a main gear is rotatably connected to the top of the motor, the main gear meshes with the secondary gear, and a bearing is fixed to the bottom of the nut through a support tube, with the bottom of the outer ring of the bearing fixedly connected to the support frame.

[0009] Preferably, a connecting groove is fixed at the rear end of the gate, the connecting groove is fastened to the truss by bolts, the truss is fastened to the inner plate, the middle plate and the gate by bolts, a sealing plate is fixed inside the sealing groove, and the sealing plate, the sealing strip and the sealing groove are fastened together by bolts.

[0010] Compared with the prior art, the beneficial effects of this utility model are: The gate of this utility model adopts an arc-shaped structure, which can disperse the impact of water flow, thereby ensuring the safety of the gate and improving its service life. The middle plate can reduce the overall weight of the gate while increasing the overall bending stiffness, thereby improving the service life of the entire gate. The truss is used to support the inner plate while ensuring the rigidity of the entire steel gate, thereby preventing the gate from deforming and improving the stability of the entire steel gate.

[0011] This invention uses a motor to drive the main gear to rotate, which in turn drives the secondary gear to rotate, which in turn drives the nut to rotate, which in turn drives the screw to rise and fall, and thus drives the gate to rise and fall, thereby changing the size of the water channel opening and thus changing the water flow. The turntable allows manual control of the screw to rise and fall when the battery is low, thereby improving the efficiency of gate control and expanding the overall application range of the steel gate.

[0012] This utility model uses a sealing groove to position the sealing strip, allowing the sealing strip to fit tightly against the guide rail, thus ensuring the overall sealing performance of the steel gate and guaranteeing the water-stopping effect. The guide rail guides the sealing groove while ensuring the stability of the gate. The anti-blocking protrusion adopts a semi-cylindrical structure, which allows the anti-blocking protrusion to bulge when not under force, thereby preventing impurities from entering the interior of the guide rail and facilitating the sealing between the sealing groove and the guide rail.

The sealing groove 305 has the sealing strip 304 slidably connected inside. The sealing strip 304 is made of rubber. The bracket 2 has a guide rail 203 inside, which guides the sealing groove 305 while ensuring the stability of the gate 3. An anti-blocking protrusion 202, also made of rubber and with a semi-cylindrical structure, is fixed inside the lower end of the guide rail 203, preventing impurities from entering the guide rail 203.This facilitates the sealing between the sealing groove 305 and the guide rail 203.

[0018] Example 2, based on Example 1, combined with... Figures 5-7 , Figure 9The water channel 1 is provided with a pouring groove 5 inside, which facilitates the positioning of the support 2. The pouring groove 5 fits tightly against the bottom of the support 2. Connecting plates 201, made of alloy material, are fixed to both ends of the support 2. The connecting plates 201 are used to position the support 2, thereby ensuring the stability of the entire steel gate. Each connecting plate 201 is fastened to the water channel 1 with bolts. A support plate 406, made of alloy material, is fixed to the top of each support 2. The support plate 406 is used to support the support frame 4. The support frame 4, made of alloy material, is fastened to the top of the support plate 406 with bolts. Made of alloy material, the support frame 4 supports the protective box 402. A solar panel 401 is fixed to the top of the support frame 4, which charges the battery 405. The protective box 402 is bolted to the top of the support frame 4. The protective box 402 is made of alloy material and is corrosion-resistant. The protective box 402 ensures the safety of the motor 605. A controller 404 is fixed inside the protective box 402. The controller 404 controls the motor 605 and can communicate with external control mechanisms. A battery 405 is fixed to the rear end of the controller 404. The battery 405 powers the motor 605. 5. Provides the required electrical energy. A sealing ring 403 is fixed to the top of the protective box 402. The sealing ring 403 is made of rubber material and can ensure the sealing of the support ring 603 and the protective box 402. The sealing ring 403 fits tightly with the support ring 603 inside it. A motor 605 is fixed to the top of the support frame 4. The motor 605 can drive the main gear 604 to rotate, thereby driving the secondary gear 606 to rotate. The main gear 604 is rotatably connected to the top of the motor 605. The main gear 604 and the secondary gear 606 are meshed. A bearing 608 is fixed to the bottom of the nut 607 through a support tube 609. The support tube 609 is made of rubber material. Made of alloy material, the bearing 608 has its outer ring bottom fixedly connected to the support frame 4. The gate 3 has a connecting groove 301 fixed at its rear end. The connecting groove 301 is used to position the middle layer plate 307 and the inner layer plate 303. The connecting groove 301 is fastened to the truss 302 by bolts. The truss 302 is fastened to the inner layer plate 303, the middle layer plate 307 and the gate 3 by bolts. A sealing plate 306 is fixed inside the sealing groove 305. The sealing plate 306 is made of alloy material and is used to position the sealing strip 304. The sealing plate 306, the sealing strip 304 and the sealing groove 305 are fastened together by bolts. Before using the steel gate, workers excavated the casting groove 5 inside the water channel 1 of the water conservancy project according to the width of the bracket 2 and the height of the anti-blocking protrusion 202. Then, workers placed the middle layer plate 307 and the inner layer plate 303 into the connecting groove 301. The gate 3, middle layer plate 307, inner layer plate 303, and truss 302 were then fastened together with bolts. Simultaneously, the truss 302 was fastened to the connecting groove 301 with bolts. Next, workers rotated the screw 6 into the nut 607 and hinged the hinge block 601 to the screw 6 using a pin. Finally, workers installed the sealing... The sealing strip 304 is inserted into the sealing groove 305. Bolts are then used to secure the sealing strip 304, the sealing groove 305, and the sealing plate 306. Further bolts are used to secure the connecting plate 201 to the water channel 1. The sealing groove 305 is then slid into the guide rail 203. Bolts are then used to secure the support frame 4 to the support plate 406. At this point, the entire steel gate begins to operate. The solar panel 401 charges the battery 405. When the height of the gate 3 needs to be changed, the controller 404 controls the motor 605 to operate, thereby driving the main gear 604 to rotate. The movement of the solar panel 401 causes the auxiliary gear 606 to rotate, which in turn causes the nut 607 to rotate, thereby raising and lowering the screw 6. The bearing 608 and the support tube 609 ensure the stability of the nut 607. During prolonged rainy weather, when the solar panel 401 cannot charge the battery 405, the operator can rotate the turntable 602 to rotate the support ring 603, which in turn causes the auxiliary gear 606 to rotate, thus changing the height of the screw 6 and increasing the usable range of the steel gate. When the controller 404 determines that the battery 405 has power but the motor 605 is not working, the operator can use the screw... The protective box 402 is opened by unscrewing the bolt, facilitating maintenance. When water stoppage is required, the controller 404 controls the motor 605 to lower the screw 6, causing the bottom sealing strip 304 to come into close contact with the anti-blocking protrusion 202. Simultaneously, the anti-blocking protrusion 202 deforms, causing the sealing groove 305 to come into close contact with the guide rail 203, thus ensuring the water stoppage effect. When the gate 003 is opened, the elasticity of the anti-blocking protrusion 202 allows it to return to its original position, preventing impurities from entering the guide rail 203 and thus extending the service life of the gate 003. This ensures the water conveyance effect of the canal 1 in the water conservancy project.

[0019] The working process of this utility model is as follows: Before using the steel gate, the workers dig the casting groove 5 inside the water channel 1 of the water conservancy project according to the width of the bracket 2 and the height of the anti-blocking protrusion 202. Then, the workers place the middle layer plate 307 and the inner layer plate 303 into the connecting groove 301. Finally, the gate 3, the middle layer plate 307, the inner layer plate 303, and the truss 302 are fastened together with bolts. Simultaneously, the truss 302 is fastened to the connecting groove 301 with bolts. Next, the workers rotate the screw 6 into the nut 607 and hinge the hinge block 601 to the screw 6 using a pin. The worker inserts the sealing strip 304 into the sealing groove 305. Bolts are then used to secure the sealing strip 304, the sealing groove 305, and the sealing plate 306. Next, bolts are used to secure the connecting plate 201 to the water channel 1. The worker then slides the sealing groove 305 into the guide rail 203. Bolts are then used to secure the support frame 4 to the support plate 406. At this point, the entire steel gate begins to operate. The solar panel 401 charges the battery 405. When the height of the gate 3 needs to be changed, the controller 404 controls the motor 605 to operate, thereby driving the main... Gear 604 rotates, thereby driving the secondary gear 606 to rotate, which in turn drives the nut 607 to rotate, thus raising and lowering the screw 6. The bearing 608 and the support tube 609 ensure the stability of the nut 607. During prolonged rainy weather, the solar panel 401 cannot charge the battery 405. In this case, the operator can rotate the turntable 602 to rotate the support ring 603, which in turn drives the secondary gear 606 to rotate, thereby changing the height of the screw 6 and increasing the usable range of the entire steel gate. When the controller 404 determines that the battery 405 has power but the motor 605 is not working, the operator... The protective box 402 is opened by unscrewing the bolts, facilitating maintenance. When water stoppage is required, the controller 404 controls the motor 605 to lower the screw 6, causing the bottom sealing strip 304 to come into close contact with the anti-blocking protrusion 202. Simultaneously, the anti-blocking protrusion 202 deforms, causing the sealing groove 305 to come into close contact with the guide rail 203, thus ensuring the water stoppage effect. When the gate 003 is opened, the elasticity of the anti-blocking protrusion 202 allows it to return to its original position, preventing impurities from entering the guide rail 203 and thus extending the service life of the gate 003. This ensures the water conveyance effect of the canal 1 in the water conservancy project.
